[" 6.If the bisector of the exterior vertical angle of a triangle be parallel to the base.Show that the triangle "],[" is isosceles."]

If the bisector of the vertical angle of a triangle bisects the base, prove that the triangle is isosceles.

If the bisector of the vertical angle of a triangle bisects the bese of the triangle;then the triangle is iscsceless.

If the bisector of the vertical angle of a triangle bisects the base of the triangle. then the triangle is isosceles. GIVEN : triangle A B C in which A D is the bisector of angle A meeting B C in D such that B D=DC TO PROVE : triangleA B C is an isosceles triangle.

If the bisector of the vertical angle of a triangle bisects the base of the triangle. then the triangle is isosceles. GIVEN : A A B C in which A D is the bisector of /_A meeting B C in D such that B D=D Cdot TO PROVE : A B C is an isosceles triangle.

If the bisector of an angle of a triangle bisects the opposite side,prove that the triangle is isosceles.

Prove that the bisector of the vertical angle of an isosceles triangle bisects the base at right angles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.
